After my wobble I am pleased to report I have been able to add album art to most of my ripped pop CDs.
The failures, which might have been due to the original rip failures or just that the tracks have not been found in MusicBrainz seem to have fallen into three categories:
CDs bought in Hong Kong with tagging attempted butt failed as I have not set up system for Chinese characters. Not a problem for me as I cannot read Chinese.
CDs bought in South Africa which are probably not in MusicBrainz.
Compilation CDs such as “Hits for the 70s” from third parties and offered by various marketing companies. Not my choice and not a problem but I was surprised that the tracks were not recognised from originals. Only a few well known titles were recognised.
None of these issues are a problem but I did then try some of my classical album genres and had almost no success. As these are often two or three CD sets of opera for example I have had to tag them all myself over the years. It was at this point but many years ago when I gave up on SongKong. The problem then was not just with your software but the database and the often arbitrary tagging suggestions uploaded. As you know, Mozart is not an Artist, he is the Composer. The Artist can be the conductor or the soloist and the debates continue.
I had been following the discussion in the Minimserver forum but had to stop and have not touched this since 2018 although I do of course run my NAS with minimserver.
The reason for posting here, in addition to thanking you once again for an excellent product in Jaikoz, is to ask if I can solve or improve my tagging of my classical collection with JaiKoz or do I have to switch to SongKong and will this help now?
